Zabbix Server

这里Zabbix Server 的ip为 : 132.232.42.144

1. 安装预备环境

sudo yum -y update
#stop SELinux
sudo sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
sudo systemctl stop firewalld.service && sudo systemctl disable firewalld.service

#install mysql57
sudo rpm -Uvh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
sudo yum install -y mysql-* --skip-broken #有冲突的软件跳过

#install Apache
sudo yum -y install httpd
sudo systemctl start httpd.service #启动
sudo systemctl enable httpd.service #开机启动
netstat -an |grep 80
#install php
sudo yum -y install php

#install php extensions
sudo yum -y install php-mysqlnd \
php-gd libjpeg* php-snmp php-ldap php-odbc php-pear \
php-xml php-xmlrpc php-mbstring php-bcmath php-mhash \
php-common php-ctype php-xml php-xmlreader php-xmlwriter \
php-session php-mbstring php-gettext php-ldap php-mysqli \
--skip-broken
sudo yum -y install \
wget telnet net-tools python-paramiko gcc \
gcc-c++ dejavu-sans-fonts python-setuptools \
python-devel sendmail mailx net-snmp \
net-snmp-devel net-snmp-utils freetype-devel \
libpng-devel perl unbound libtasn1-devel \
p11-kit-devel OpenIPMI unixODBC

sudo chmod o+w /etc/my.cnf
# set php config
sudo cat <<EOM >> /etc/my.cnf
innodb_file_per_table = 1
innodb_status_file = 1
innodb_buffer_pool_size = 1600M
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 64M
innodb_support_xa = 0
default-storage-engine = innodb
bulk_insert_buffer_size = 8M
join_buffer_size = 16M
max_heap_table_size = 32M
tmp_table_size = 32M
max_tmp_tables = 48
read_buffer_size = 32M
read_rnd_buffer_size = 16M
key_buffer_size = 32M
thread_cache_size = 32
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT

sudo chmod o-w /etc/my.cnf
cat /etc/my.cnf
#注:原则上 innodb_buffer_pool_size 需要设置为主机内存的 80%,
#innodb_log_buffer_size 建议设置为 32M,
#innodb_log_file_size 建议设置为 128M,
#innodb_buffer_pool_size的值必须是整数,例如主机内存是4G,那么innodb_buffer_pool_size可以设置为3G,而不能设置为3.2G
#start mysql
sudo systemctl enable mysqld && sudo systemctl start mysqld
mysql_secure_installation #初始化数据库信息

2. 安装zabbix并导入zabbix数据库信息

#创建zabbix数据库,创建zabbix账号 
grep "password" /var/log/mysqld.log #初次安装mysql,这一步可以看到mysql的root密码
mysql -uroot -p #完成后输入mysql root密码
create database zabbix character set utf8; 
create user zabbix@'%' identified by 'hnbd@2018'; #创建用户和密码
grant all privileges on zabbix.* to zabbix@'%'; #赋权
flush privileges;
exit;

#install Zabbix source: http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/
sudo rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm 
#install Zabbix 
sudo yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-java-gateway zabbix-web
#import Zabbix info
cd /usr/share/doc/zabbix-server-mysql-3.0.20
#导入默认的zabbix数据库信息
zcat create.sql.gz | mysql -uzabbix zabbix -phnbd@2018

3. 修改zabbix_server.conf的配置文件

sudo vim /etc/zabbix/zabbix_server.conf

修改以下内容为自己的配置

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

CacheSize=512M
#(CacheSize在371行)
HistoryCacheSize=128M
#(HistoryCacheSize在397行)
HistoryIndexCacheSize=128M
#(HistoryIndexCacheSize在405行)
TrendCacheSize=128M
#(TrendCacheSize在414行)
ValueCacheSize=256M
#(ValueCacheSize在425行)
Timeout=30
#(Timeout在432)
#其它参数保持默认值即可

#如果需要监控VMware虚拟机,则还需要设置以下选项参数:
StartVMwareCollectors=2
#(StartVMwareCollectors在272行
VMwareCacheSize=256M
#(VMwareCacheSize 在298行)
VMwareTimeout=300
#(VMwareTimeout在306行)

4. 修改zabbix.conf

sudo vim /etc/httpd/conf.d/zabbix.conf

修改以下内容为自己的配置

php_value max_execution_time 600
php_value memory_limit 256M
php_value post_max_size 32M
php_value upload_max_filesize 32M
php_value max_input_time 600
php_value always_populate_raw_post_data -1
php_value date.timezone Asia/Shanghai

5. 启动apache/zabbix-server服务

#restart httpd and check port
sudo systemctl restart httpd
netstat -an |grep 80
#start Zabbix
sudo systemctl start zabbix-server
sudo systemctl enable zabbix-server
#check log of Zabbix
tailf  /var/log/zabbix/zabbix_server.log
#check dir of Zabbix
ls /usr/share/zabbix

启动后需要一些配置信息,这些信息填写后存储在/etc/zabbix/web/zabbix.conf.php

vi /etc/zabbix/web/zabbix.conf.php
<?php
// Zabbix GUI configuration file.
global $DB;

$DB['TYPE']     = 'MYSQL';
$DB['SERVER']   = '132.232.42.144';
$DB['PORT']     = '0';
$DB['DATABASE'] = 'zabbix';
$DB['USER']     = 'zabbix';
$DB['PASSWORD'] = 'hnbd@2018';

// Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = '';

$ZBX_SERVER      = '132.232.42.144';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = '132_232_42_144';

$IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;

部署Zabbix Agent

将下面的 132.232.42.144 换成自己 Zabbix Server 的ip

sudo rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm 
#install Zabbix 
sudo yum -y install zabbix-agent

#set zabbix agent config
# vim /etc/zabbix/zabbix_agentd.conf
# Server=132.232.42.144                   #用于被动模式,数据获取
# ServerActive=132.232.42.144             #用于主动模式,数据提交
sudo sed -i 's/^Server=.*/Server=132.232.42.144/g' /etc/zabbix/zabbix_agentd.conf
sudo sed -i 's/^ServerActive=.*/ServerActive=132.232.42.144/' /etc/zabbix/zabbix_agentd.conf

sudo systemctl start zabbix-agent
sudo systemctl enable zabbix-agent
